Our mosquito repellent band uses a dual protection mechanism: 1) Ultrasonic technology - emits specific frequency sound waves to interfere with mosquito perception systems; 2) Natural essential oil slow release - slowly releases natural ingredients such as citronella oil and eucalyptus oil through silicone material to form a scent barrier around the skin. The combination of both can provide up to 72 hours of effective protection.

Completely safe. Our mosquito repellent band uses pure physical mosquito repellent technology, contains no chemical mosquito repellents (such as DEET), and achieves mosquito repellent effects through natural plant essential oils. The product has passed multiple safety tests and can be used with confidence by pregnant women and children.

The entire SmartBand product line reaches IP68 water resistance rating and can function normally for 30 minutes at a depth of 1.5 meters. It can be worn during daily hand washing, showering, and swimming, but is not recommended for use in extreme environments such as hot baths, saunas, or deep diving.

It is recommended to gently wipe the strap surface with a soft damp cloth weekly. For stubborn stains, gently wipe with a small amount of neutral detergent, then rinse with clean water and dry. Avoid using chemical solvents such as alcohol and bleach for cleaning to prevent damage to the strap material.

The standard SmartBand can last up to 14 days, and the Ultra version can last up to 30 days. When the battery level drops below 10%, the device will remind you to charge through vibration and screen notification. Using the accompanying magnetic charging cable, it can be fully charged in 1.5 hours.

The essential oil core of the mosquito repellent band is located on the inner side of the strap and can be easily removed and replaced. When the mosquito repellent effect significantly weakens (usually after 30-45 days of use), please follow the instructions to open the strap buckle, remove the old essential oil core and replace it with a new one. It is recommended to replace it every 30 days to ensure optimal effectiveness.
